3d相机-如何更改相机方向？
[英]3d Camera - How to Change Camera Orientation?
问题描述
Say I have a world object at point W and a camera at point C. How do I make the camera point at the object? 
假设我在W点有一个世界对象，而在C点有一个摄像机。如何使摄像机指向该对象？
If I have one vector UP that is (0,2,0) how do I show the rotation matrix for this camera? 如果我有一个向量UP为（0,2,0），如何显示此摄像机的旋转矩阵？
Any helpful references would be appreciated, Thanks! 任何有用的参考将不胜感激，谢谢！

Particularly the "Following Targets" section where it shows how to get the camera vectors for looking at an arbitrary point. 特别是“跟随目标”部分，其中显示了如何获取用于观察任意点的摄像机矢量。
